I'm using NV3 and upgraded to NV4 for Davinci Resolve.
NV3 has perfect accuracy of temporal filter (especially with radius=5)
NV4 does blurry spots, lost details and result look far worse than preview.

Sorry for big picture.

My Cuda 5.2 videocard is not supported in NV3 and nextgen version works inaccuracy.

1. Make sure you build the noise profile correctly, that is most important.

2. Check preview inside Resolve's window, not in Neat Video, because Resolve does not provide all input frames required to prepare accurate preview (specifically, the temporal filter cannot work without those missing input frames). In Resolve preview, the filter is able to receive all input frames and prepare correctly processed preview.

Noise profile is correct. I'm using NV for years and purchased 3 copies.

NV3 temporal filter works perfect without losing details but CUDA 5.2 unsupported.
NV4 is unacceptable because of that blurry areas with losing details.

Please prepare a reproducible test case - a small project showing both NV3 and NV4 on a short test clip. We will run it on our machines and check what exactly is causing the problem. It most likely can be avoided or fixed.
Please send that test case to support [at] neatvideo.com

If you want to try v3 with 5.2 support please also send a request to support [at] neatvideo.com

To compare results like this they have to be prepared based on the same noise profiles and with the same filter settings. We will download the files and check if these conditions are satisfied in the test project.
